💡 Enhancements 💡

• cmd/builder: Allow for replacing of local Providers and Converters when building custom collector with ocb. (#​11649)
  Use the property path under gomod to replace an go module with a local folder in
  builder-config.yaml. Ex:
  providers:
  - gomod: module.url/my/custom/provider v1.2.3
  path: /path/to/local/provider

• cmd/builder: Allow configuring confmap.Converter components in ocb. (#​11582)
  If no converters are specified, there will be no converters added.
  Currently, the only published converter is expandconverter which is
  deprecated as of v0.107.0, but can still be added for testing purposes.

  To configure a custom converter, make sure your converter implements the converter
  interface and is published as a go module (or replaced locally if not published).
  You may then use the converters key in your OCB build manifest with a list of
  Go modules (and replaces as necessary) to include your converter.

  Please note that converters are order-dependent. The confmap will apply converters
  in order of which they are listed in your manifest if there is more than one.

• all: shorten time period before removing an unmaintained component from 6 months to 3 months (#​11664)

🧰 Bug fixes 🧰

• all: Updates dialer timeout section documentation in confignet README (#​11685)
• scraperhelper: If the scraper shuts down, do not scrape first. (#​11632)
  When the scraper is shutting down, it currently will scrape at least once.
  With this change, upon receiving a shutdown order, the receiver's scraperhelper will exit immediately.

• configtelemetry: Add 10s read header timeout on the configtelemetry Prometheus HTTP server. (#​5699)

• service: Allow users to disable the tracer provider via the feature gate service.noopTracerProvider (#​10858)
  The service is returning an instance of a SDK tracer provider regardless of whether there were any processors configured causing resources to be consumed unnecessarily.

• confmap: When passing configuration for a string field using any provider, use the verbatim string representation as the value. (#​10605, #​10405)
  This matches the behavior of ${ENV} syntax prior to the promotion of the confmap.unifyEnvVarExpansion feature gate
  to beta. It changes the behavior of the ${env:ENV} syntax with escaped strings.

v0.104.0

Compare Source

This release includes 2 very important breaking changes.

1. The otlpreceiver will now use localhost by default instead of 0.0.0.0. This may break the receiver in containerized environments like Kubernetes. If you depend on 0.0.0.0 disable the component.UseLocalHostAsDefaultHost feature gate or explicitly set the endpoint to 0.0.0.0.
2. Expansion of BASH-style environment variables, such as $FOO will no longer be supported by default. If you depend on this syntax, disable the confmap.unifyEnvVarExpansion feature gate, but know that the feature will be removed in the future in favor of ${env:FOO}.

🛑 Breaking changes 🛑

• filter: Remove deprecated filter.CombinedFilter (#​10348)
• otelcol: By default, otelcol.NewCommand and otelcol.NewCommandMustSetProvider will set the DefaultScheme to env. (#​10435)
• expandconverter: By default expandconverter will now error if it is about to expand $FOO syntax. Update configuration to use ${env:FOO} instead or disable the confmap.unifyEnvVarExpansion feature gate. (#​10435)
• otlpreceiver: Switch to localhost as the default for all endpoints. (#​8510)
  Disable the component.UseLocalHostAsDefaultHost feature gate to temporarily get the previous default.

💡 Enhancements 💡

• confighttp: Add support for cookies in HTTP clients with cookies::enabled. (#​10175)
  The method confighttp.ToClient will return a client with a cookiejar.Jar which will reuse cookies from server responses in subsequent requests.
• exporter/debug: In normal verbosity, display one line of text for each telemetry record (log, data point, span) (#​7806)
• exporter/debug: Add option use_internal_logger (#​10226)
• configretry: Mark module as stable. (#​10279)
• debugexporter: Print Span.TraceState() when present. (#​10421)
  Enables viewing sampling threshold information (as by OTEP 235 samplers).
• processorhelper: Add "inserted" metrics for processors. (#​10353)
  This includes the following metrics for processors:
  • processor_inserted_spans
  • processor_inserted_metric_points
  • processor_inserted_log_records

• otelcol/expandconverter: Add confmap.unifyEnvVarExpansion feature gate to allow enabling Collector/Configuration SIG environment variable expansion rules. (#​10391)
  When enabled, this feature gate will:
  • Disable expansion of BASH-style env vars ($FOO)
  • ${FOO} will be expanded as if it was `${env:FOO}
    See https://github.com/open-telemetry/opentelemetry-collector/blob/main/docs/rfcs/env-vars.md for more details.
• confmap: Add confmap.unifyEnvVarExpansion feature gate to allow enabling Collector/Configuration SIG environment variable expansion rules. (#​10259)

• confighttp: Allow the compression list to be overridden (#​10295)
  Allows Collector administrators to control which compression algorithms to enable for HTTP-based receivers.
• configgrpc: Revert the zstd compression for gRPC to the third-party library we were using previously. (#​10394)
  We switched back to our compression logic for zstd when a CVE was found on the third-party library we were using. Now that the third-party library has been fixed, we can revert to that one. For end-users, this has no practical effect. The reproducers for the CVE were tested against this patch, confirming we are not reintroducing the bugs.
• confmap: Adds alpha confmap.strictlyTypedInput feature gate that enables strict type checks during configuration resolution (#​9532)
  When enabled, the configuration resolution system will:
  • Stop doing most kinds of implicit type casting when resolving configuration values
  • Use the original string representation of configuration values if the ${} syntax is used in inline position
• confighttp: Use confighttp.ServerConfig as part of zpagesextension. See server configuration options. (#​9368)

🛑 Breaking changes 🛑

• envprovider: Restricts Environment Variable names. Environment variable names must now be ASCII only and start with a letter or an underscore, and can only contain underscores, letters, or numbers. (#​9531)
• confighttp: Apply MaxRequestBodySize to the result of a decompressed body. This addresses GHSA-c74f-6mfw-mm4v for confighttp (#​10289)
  When using compressed payloads, the Collector would verify only the size of the compressed payload.
  This change applies the same restriction to the decompressed content. As a security measure, a limit of 20 MiB was added, which makes this a breaking change.
  For most clients, this shouldn't be a problem, but if you often have payloads that decompress to more than 20 MiB, you might want to either configure your
  client to send smaller batches (recommended), or increase the limit using the MaxRequestBodySize option.

🛑 Breaking changes 🛑

• builder: Add strict version checking when using the builder. Add the temporary flag --skip-strict-versioning for skipping this check. (#​9896)
  Strict version checking will error on major and minor version mismatches
  between the otelcol_version configured and the builder version or versions
  in the go.mod. This check can be temporarily disabled by using the --skip-strict-versioning
  flag. This flag will be removed in a future minor version.

• telemetry: Distributed internal metrics across different levels. (#​7890)
  The internal metrics levels are updated along with reported metrics:

  • The default level is changed from basic to normal, which can be overridden with service::telmetry::metrics::level configuration.
  • Batch processor metrics are updated to be reported starting from normal level:
    • processor_batch_batch_send_size
    • processor_batch_metadata_cardinality
    • processor_batch_timeout_trigger_send
    • processor_batch_size_trigger_send
  • GRPC/HTTP server and client metrics are updated to be reported starting from detailed level:
    • http.client.* metrics
    • http.server.* metrics
    • rpc.server.* metrics
    • rpc.client.* metrics

💡 Enhancements 💡

• confighttp: Disable concurrency in zstd compression (#​8216)

• cmd/builder: Allow configuring confmap.Providers in the builder. (#​4759)
  If no providers are specified, the defaults are used.
  The default providers are: env, file, http, https, and yaml.

  To configure providers, use the providers key in your OCB build
  manifest with a list of Go modules for your providers.
  The modules will work the same as other Collector components.

• mdatagen: enable goleak tests by default via mdatagen (#​9959)

• cmd/mdatagen: support excluding some metrics based on string and regexes in resource_attributes (#​9661)

• cmd/mdatagen: Generate config and factory tests covering their requirements. (#​9940)
  The tests are moved from cmd/builder.

• confmap: Add ProviderSettings, ConverterSettings, ProviderFactories, and ConverterFactories fields to confmap.ResolverSettings (#​9516)
  This allows configuring providers and converters, which are instantiated by NewResolver using the given factories.
